Description
General part information
BQ24640 Series
The bq24640 device is a highly integrated switched-mode super capacitor charge controller. The device offers a constant-frequency synchronous PWM controller with high accuracy charge current, voltage regulation, and charge status monitoring.
The bq24640 charges a super capacitor in two phases: constant current and constant voltage (CC/CV). The device can charge super capacitors from 0 V with current set on the ISET pin. When the super capacitor voltage reaches the programmed target voltage, charge current begins tapering down.
The bq24640 enters a low-current sleep mode(<15 µA) when the input voltage falls below the output capacitor voltage.
